    When I want lasagna, I want unmistakable comfort food.  This keto lasagna definitely fits the bill because it is nothing but the good stuff.  No zucchini pasta to be found!  The best part is this low carb lasagna recipe can be made any night of the week.  It's that easy!

    Keto lasagna in a casserole dish

    I am all about keto dinners that my whole family will eat.  If I were to have put zucchini noodles or cabbage noodles in this keto lasagna...they would have turned their nose up really quickly.  I could have used homemade keto noodles or egg life wraps, but I really do not think they are needed and add to the calories in this dish.

    Making lasagna low carb friendly doesn't take hardly any effort because all you really have to do is remove the noodles.  By doing that, and using only 24 ounces of a low carb marinara sauce and 15 ounces of ricotta, we are able to get this keto lasagna down to 8 net carb per serving.

    It is super filling on it's own so I really wouldn't pair it with any side.  You could serve with a side salad for a vegetable since this is kind of heavy.

    I love to use a combo of ground beef and ground sausage for a delicious a full of flavor meat sauce.  It really kicks this keto lasagna up a notch!

    Ingredients needed

    This section explains how to choose the best ingredients for this keto lasagna recipe, what each one does in the recipe, and substitution options. For a printable recipe, see the recipe card below.

    1 pound ground Italian sausage - I like to use mild Italian sausage for this keto lasagna but you could also use medium or hot sausage.  I love the flavor the sausage gives to the lasagna!

    1 pound ground beef - I like to use a lean ground beef since we are already using so many other rich ingredients.

    ½ cup diced onion

    1 teaspoon minced garlic

    salt and pepper

    24 ounces Rao's marinara sauce - This sauce is really low in carbs and tastes amazing in low carb lasagna! I love that it is uses simple ingredients (tomatoes, olive oil, onions, salt, garlic, basil, black pepper and oregano)

    15 ounces ricotta cheese - you could use low fat ricotta or full fat.  They both have the same amount of carbs.

    2 large eggs

    1 teaspoon dried Italian seasoning

    ½ teaspoon minced garlic

    2 cups shredded mozzarella cheese

    1 ½ cups shredded parmesan cheese

    How to make keto lasagna

    This section explains how to make this low carb lasagna recipe, step by step. For a full printable recipe, see the recipe card below.

    Step 1 - Preheat the oven to 375F.  In a large pot or large skillet over medium high heat, brown and crumble the sausage and ground beef with the onion and garlic, drain any excess grease. Season with salt and pepper to taste. Stir in the marinara. Remove from the heat and set aside.

    Step 2 - In a separate medium bowl, mix together the ricotta, eggs, Italian seasoning, garlic, and 1 cup of the parmesan cheese.

    Step 3 - In a large 9x13 casserole dish or large baking dish, layer half of the meat mixture in the bottom. layer all of the ricotta mixture on top.

    Step 4 - Now the rest of the meat mixture goes on top of the ricotta mixture

    Step 5 - Finish off by sprinkling the mozzarella and the remaining ½ cup of parmesan.

    Step 6 - Bake in the pre-heated oven for 30 minutes. Remove from oven and let rest for 10 minutes before serving.

    What could I use as keto noodles?

    • I have seen people make their own keto lasagna noodles out of cheese.  In my opinion that is just too much cheese and adds lots of extra calories.
    • You could use egg life wraps cut into strips
    • I have heard of people using lunch meat
    • Of course there is zucchini lasagna noodles which is very common
    • A commenter let me know they now have hearts of palm pasta that is very similar to lasagna noodles. Those are definitely worth a try.

    Tips for the best low carb lasagna

    • Double the recipe for 2 keto lasagnas and freeze one of them for later. (freezing instructions below)
    • Add some fresh basil in the sauce to perk up the flavor.
    • Add in slices of provolone cheese for even more cheesy goodness!
    • Use one of the noodle options above for more familiarity and structure.

    How to freeze this keto lasagna recipe

    If you want to freeze the whole keto lasagna, assemble it in a foil 9x13 baking pan and then wrap tightly with foil.  Place in the freezer and keep frozen for up to 2 months.  When you are ready to serve it, remove it from the freezer and bake in the oven until the internal temperature reaches 165F.

    You can also freeze a single portion for meal prep.

      I made this for dinner tonight, and it is delicious. Thank you! I had some disposable personal size aluminum pans that I divided the ingredients amongst, and then baked them in the air fryer. They turned out perfectly. Tomorrow I will be doing the same thing with your trustless keto pizza.

      Is it grated or shredded Parmesan cheese?

      Love this recipe. Have made it several times. For structure I use Folios cheese wraps. I cut 2-3 of them in half (depending on the size of the casserole dish), align the straight edge of the wraps with the outer edge of the dish, layer in the meat and ricotta mixture, then another layer of Folios, then the remaining meat. Top with the cheese and bake. The Folios help keep the whole thing from becoming mush. I use the parmesan flavored ones.

      No noodles sounds great to me -- just the meat and cheese and veggies. It is now a lasagna bowl.
